As you know, you have update problems, that we are trying to fix...
Without the update working, you could not download the prices information (updated daily), that's why you don't have any price at all.
Personally, if I mark "Ghost Rider" as wished, I get 6 price results (1 UMD, 1 BLU-RAY, and 4 DVDs).
Hopefully we'll soon have resolved the mystery of your update troubles.
